Beside etherscan.io, is there anywhere a full ownership structure with percentage on how many coins get moved across accounts, how many of them go to exchanges etc? So we can calculate exact free float of the coin? After all, it is a blockchain coin :)

Kind of agree myself. I trade ETH/USD as, I believe, the ratio implies too much risk with the Chinese Yuan devaluation and the government potential to police Bitcoin transfers and think that if the ratio goes up it will be a result of ETH strength as opposed to a Bitcoin decline...
